Question

Find the x- and y-intercept of the line. −75x − 4y = 7

a.x-intercept is 74

; y-intercept is 5


b.x-intercept is −74

; y-intercept is 5


c.x-intercept is 5; y-intercept is 74



d.x-intercept is -5; y-intercept is −74

Answer 1

To solve this problme you must apply the proccedure shown below:
1. To find the x-intercept y must be zero, so, you have:
−75x − 4y = 7
y=0
−75x=7
x=-7/75 (x-intercept)

2. To find the y-intecept x must be zero, then, yo have:
x=0
−75x − 4y= 7
-4y=7
y=-7/4 (y-intercept)
